HTTPS with FreeDNS (self.selfhosted)

I feel like I have a doozy of a complicated issue and am looking for some guidance.

I'm new to Selfhosting so I got myself an off-the-shelf Asustor NAS. It's got apps which is cool, so I've installed Jellyfin. I want to access my Jellyfin over the web so I've set up DDNS via my Asusstor Manual Connect and FreeDNS. This works well, I can access it over HTTP but the domain is... kind of long and unpleasant, so I got myself a "pretty" domain and setup a CNAME to the FreeDNS. I'm port forwarding on my router, everything works, so far so good.

To make it overtly complicated, I want to make the connection HTTPS. This is where I'm struggling. I've set up the SSL cert for my "pretty" domain via Lets Encrypt, but it times out. I'm not sure if, or how I can make the FreeDNS HTTPS or covered under my Lets Encrypt cert since I don't technically own the FreeDNS domain. My provider doesn't give my any wildcard options on the "pretty" domains cert either.

I've got the HTTPS set on my Asustor and Jellyfin based on the "pretty" domains SSL cert. I've got my port-forwarding 443 to Jellyfins suggested HTTPS port on my router. I feel like the lynchpin is the FreeDNS subdomain handing off the DDNS request but I'm not sure how to solve it. Any suggestions on how I can get this setup to work? Anyone else run a similar setup where they access their local X port via the web via HTTPS?

Open to similar experiences, suggestions, ideas, pretty much anything at this point.

I do have port 80 open as well as 443, both going to my Jellyfin HTTP/HTTPS ports respectively. HTTP seems to work for both when I access "pretty" domain and the FreeDNS URLs directly. It's really only when I try to force HTTPS that I'm having issues.

I'll play around with Let's Encrypt today to see if I can get the FreeDNS cert applied. I've tried to use AI to assist me in learning how to do all this, it suggests I need both my "pretty" domain and the FreDNS domain tied to the same Cert, which Im unable to do at my current domain registrar, so I might also need to move that but I'll take it one step at a time.
